Petratos and George both collected 26 points with Sydney FC striker Bobo (24) and Adelaide United skipper Isaias (20) rounding out the top five.

After each regular season round, votes were cast by a panel that included former professional players, technical experts, match officials and media representatives.

It became obvious early in the season that Mierzejewski would be a front-runner for the award with his silky skills and attacking ability eventually driving the Sky Blues to a second consecutive Premiership.

In his debut year in the Hyundai A-League, the former Polish international played 25 matches, scoring 13 goals and laying on a further nine assists.

He led Sydney FC in assists, crossing and dribbling and created 49 chances across the season.

Mierzejewski's passing accuracy was 79%, dropping only slightly to 75% in the attacking half.

Furthermore, his shooting accuracy was an impressive 71%.

Earlier this season, Mierzejewski won the Mark Viduka medal for player of the match in the FFA Cup final and was also named player of the year by broadcaster Fox Sports.

It also marked successive Johnny Warren Medals for Sydney FC with Milos Ninkovic claiming the top gong last season.
